ABSTRACT:
A modulating system for a rotary hermetic compressor is provided with a valve operable by a force varying with the difference in pressure between the suction and discharge pressure for allowing a portion of the refrigerant gas being compressed to travel from the compression side of the roller to the suction side of the roller when the design peak load of the compressor is exceeded.
